LOST CIRCULATION COMPOSITION FOR FRACTURE SEALING |
摘要 |
A lost circulation material and method for well treatment employing the material that is effective at sealing or plugging fractured zones and has utility over a wide range of temperatures, including high temperatures. The lost circulation material includes particulate material to quickly de-fluidize the fluid formulation, fibrous material to suspend particles in the slurrified form of the composition and increase the shear strength of the resultant seal, and non-Portland cement material for increasing the compressive strength. |
